Five festivals have been cancelled in New South Wales (NSW) and Victoria due to the ongoing catastrophic bushfires that have ravaged Australia over the past month.

According to Pollstar, the worsening conditions have sparked further concern in the industry for the future of regional summer festivals moving forward.

Lost Paradise in Glenworth Valley, which was scheduled to take place from December 28 to January 1, cancelled the event two weeks prior, while Lunar Electric in Maitland on January 4 opted to postpone the event two days before it kicked off.

Yours & Owls pulled its January 1 Day of Dance to free up WIN Stadium and WIN Entertainment Centre in Wollongong for emergency relief.

In Victoria, the December 28 to 31 Lorne stop of the four-state Falls Festival cancelled the last two days and evacuated 9,000 campers. Thee Unified Gathering, which is due to kick off tomorrow (Wednesday), was still going ahead at press time but monitoring the situation.

Rainbow Serpent, which is scheduled for the end of the month, ceased ticket sales after parts of its site were burned (pictured), but will go ahead after changes to the site layout.
